[0002] The beet leaf remover and topper is an agricultural machine specially used for leaf removing and topping operations during the beet harvesting process. The use of this machine can greatly improve the efficiency of beet harvesting, reduce the labor intensity of farmers, and help improve the yield and quality of beets. The beet leaf remover and topper is usually composed of a frame, a power transmission mechanism, an impeller assembly, a topper assembly, a height limiting wheel assembly and other components. It is usually used in conjunction with a wheeled tractor, and the tractor provides power to drive the impeller and the topper to work. The existing beet leaf remover and topper is usually hinged at the tail end of the frame with multiple topper cutters. During the movement of the equipment, it is usually necessary to use a lifting rope to lift each topper separately to avoid damage to the topper during the movement of the device. After the equipment arrives at the working area, the lifting ropes need to be removed one by one, and the topper needs to be put down to work. This process is relatively wasteful of manpower and reduces work efficiency. Therefore, it is necessary to develop an efficient beet leaf remover and topper device that can simultaneously control all topper cutters to rise or fall synchronously to improve work efficiency.
